The key sizes 40 bits and 104 bits correspond to WEP encryption, so the 
card definitely seems to support it.

As for the security mode, from the iwconfig man pages:

"The security mode may be open or restricted, and its meaning depends on 
the card used. With  most  cards, in  open  mode  no authentication is 
used and the card may also accept non-encrypted sessions, whereas in 
restricted mode only encrypted sessions are accepted and the card will 
use authentication if available."

You can manually set the encryption keys and security mode with 
iwconfig.  I don't know what graphical app ubuntu uses for configuring 
wireless.
